The verdict in three sentences
Before committing to a five-figure rebuild, a performance audit at 900-3,500 € pinpoints where leads really leak. Its deliverables — Lighthouse report, prioritized action plan, quick wins — turn a hunch into a budgeted decision. For a marketing director it's insurance: well targeted, the audit avoids 30 to 50 % of a rebuild budget that would have fixed the wrong problems.
Audit types and their deliverables
Not all audits are equal. Scope drives price, timeline and, above all, how actionable the recommendations are.
| Audit type | Scope | 2026 price | Timeline |
|---|---|---|---|
| Performance audit | Lighthouse, Vitals, weight, cache | 900 - 3,500 € | 1 - 2 wk |
| Perf + SEO audit | + crawl, tags, internal links | 1,800 - 4,500 € | 2 - 3 wk |
| Perf + SEO + accessibility | + WCAG 2.1 AA, contrasts | 2,500 - 6,000 € | 2 - 3 wk |
| Express audit (quick wins) | Diagnostic + 5 actions | 900 - 1,500 € | 3 - 5 days |
The deliverable that matters isn't the raw report but the prioritized action plan: each problem ranked by impact and effort, with an estimated fix cost — the basis of a realistic rebuild quote.
What the audit saves
An audit isn't a comfort expense: it's a filter that avoids paying for useless fixes and focuses the budget where it pays off.
| Benefit | Without audit | With audit |
|---|---|---|
| Fix targeting | Approximate | Prioritized by ROI |
| Rebuild budget committed | 100 % | 50 - 70 % (targeted) |
| Risk of redoing the useless | High | Low |
| Immediate quick wins | Rare | 3 to 5 identified |
| Rebuild go / no-go decision | Intuition | Field data |
On a rebuild considered at 15,000 €, a 2,500 € audit revealing that 60 % of gains come from three targeted fixes can bring the project down to 6,000-9,000 € — the audit repays itself several times over.
Mini case study
Claire, marketing director of a digital services SME in Lyon, sees a 68 % bounce rate and a declining lead flow without knowing why. She orders a perf + SEO audit at 3,200 €. The report reveals three causes: LCP at 4.4 s (unoptimized images), a broken mobile form and poor internal linking. Instead of a 15,000 € rebuild, she commits 5,500 € of targeted fixes. Saving on the rebuild budget: 9,500 €, nearly 3 times the audit cost, while recovering the lead flow within two months.

FAQ
Is an audit really necessary before a rebuild?
Yes, whenever the rebuild budget exceeds 8,000 €. The 900-3,500 € audit avoids funding useless fixes and targets the 20 % of problems responsible for 80 % of losses.
What deliverables will I concretely receive?
A commented Lighthouse report, an action plan prioritized by impact/effort, a quick-wins list and, depending on scope, an SEO and WCAG 2.1 AA accessibility section. All usable to quote a rebuild.
How long does an audit take?
From 3-5 days for an express audit to 2-3 weeks for a full perf + SEO + accessibility audit. Timeline depends on the number of pages and crawl depth.
Does the audit include fixing the problems?
No: the audit diagnoses and prioritizes; fixes are a separate quote. Some quick wins can, however, be applied immediately as part of an express audit.
How do I know which audit type to choose?
If the problem is clearly speed, a 900-3,500 € performance audit is enough. If leads drop with no identified cause, the 2,500-6,000 € perf + SEO + accessibility audit covers every blind spot.
